Pancyclicity of Matching Composition Networks under the Conditional Fault Model.

A graph G=(V,E) is said to be \emph{conditional k-edge-fault pancyclic} if, after removing $k$ faulty edges from $G$ and provided that each node is incident to at least two fault-free edges, the resulting graph contains a cycle of every length from its girth to $|V|$ inclusive. In this paper, we sketch the common properties of a class of networks called Matching Composition Networks (MCNs), such that the conditional edge-fault pancyclicity of MCNs can be determined from the derived properties. We then apply our technical theorem to show that an $m$-dimensional hyper-Petersen network is conditional $(2m-5)$-edge-fault pancyclic. \\ \noindent{\bf Keywords}: Conditional edge faults, fault-tolerant cycle embedding, matching composition networks, pancyclicity, multiprocessor systems.
